摘　　要：　光纤陀螺是一种敏感的、相对于惯性空间角运动的新型传感器。本文研究了计数式光纤陀螺输出信号模拟的方法、电路设计及计数卡的具体实现电路和软件编程方法。设计的信号模拟电路精确模拟了光纤陀螺输出信号的波形,给计数卡提供了准确的输入测试信号。设计的计数卡具有电路简单、精度高的特点,通过对实际陀螺的测试,正确可靠。Fiber-optic gyro is a kind of new sensitive sensor, moving relative to inertial space angle. This paper presents the simulation method and the circuit design of output signal for counting type fiber-optic gyro, and the realization circuit and software programming method of counter card. The designed signal simulation circuit can precisely simulate the output signal waveform of fiber-optic gyro, offer accurate input signal to counter card. The counter card is simple and accurate, and has been proved to be effective and reliable through testing on real gyro.
